Last weekend I found a 3 speed Saginaw OD unit out of a '67 Chevelle I'm going to put in my '72 to replace one that's starting to fail (non-over drive). Does anyone have a wiring diagram for the '67? I look in some old manuals I have from the '70's and I found a wiring diagram for a AMC overdrive but the wires aren't color coded in the diagram.

Thanks - Don
